Need for spinal immobilization - consider the following guidelines:
1. Long spine boards (LSB) have both risks and benefits for patients and have not been shown to improve outcomes. The best use of the LSB may be for extricating the unconscious patient, or providing a firm surface for compressions.
Preferred immobilization devices in order of preference are:


  1. Cervical collar and strapped to gurney in position of comfort




  1. Vacuum Mattress with cervical collar




  1. Combi-Carrier/Scoop Stretcher with cervical collar/CID/Spider Straps




  1. KED/Clamshell Extrication device with cervical collar




  1. Long Spine board with cervical collar/CID/Spider Straps

2. Adequate spinal precautions may be achieved by placement of a hard cervical collar and ensuring that the patient is secured tightly to the stretcher, ensuring minimal movement and patient transfers, and manual in-line stabilization during any transfers.


3. Utilization of the spinal immobilization should occur in consideration of the individual patient's benefit vs. risk.
4. Patients with penetrating trauma and no evidence of spinal injury do not require spinal immobilization.

RAPID SEQUENCE INTUBATION/SURGICAL AIRWAY POLICY
The use of this protocol is indicated in patients with compromised airways or impending respiratory failure who cannot be successfully intubated due to intact gag reflex.
Ventilate with 100% Oxygen using Bag-Valve-Mask & simple airway adjuncts

Most patients can be ventilated with basic techniques


In spontaneously breathing patients, apply Nasal Cannula and NRB Mask at 15 LPM for a minimum of 3 minutes prior to sedation/paralysis. If patient fails to maintain a SpO2 of 94% or better, consider replacing NRB mask with CPAP or BVM assisted ventilation
Retain Nasal Cannula at 15 LPM after removal of NRB Mask/CPAP/BVM for induction/paralysis
Induction

Administer Etomidate 0.3 mg/kg IV/IO for sedation

(Pediatric dose per weight/length-based system)

or

Midazolam 2-4 mg IV/IO



(Pediatric patients – utilize weight/length-based system)

or

Ketamine 1.5 mg/kg IV/IO



(Pediatric patients – utilize weight/length-based system)
Consider attempting oral endotracheal intubation prior to Neuromuscular paralysis
Neuromuscular Paralysis

Administer Succinylcholine 1.0 mg/kg IV/IO - maximum dose 150 mg

(Pediatric dose per weight/length-based system)

or

Administer Vecuronium 0.1 mg/kg rapid IV/IO



(Pediatric dose per weight/length-based system)

or

Administer Rocuronium 0.6 mg/kg rapid IV/IO



(Pediatric dose per weight/length-based system)
Watch for signs of muscle flaccidity, and then attempt oral endotracheal intubation

If unable to intubate after three (3) attempts – place a supraglottic airway or perform Surgical Cricothyrotomy


Attach end tidal CO2 in-line monitoring connecter. Continue ventilation with 100% Oxygen using Bag-Valve Device or mechanical ventilator

To maintain Sedation:

Administer Ketamine 1.5 mg/kg IV/IO, repeat every 15 mins.

(Pediatric dose per weight/length-based system)

or

Administer Midazolam 2 – 3 mg, repeat every 15 mins.



(Pediatric dose per weight/length-based system)

Consider concurrent pain management – See Pain Management policy


To maintain Paralysis:

Administer Vecuronium 0.1 mg/kg rapid IV/IO

(Pediatric dose per weight/length-based system)

or

Administer Rocuronium 0.6 mg/kg rapid IV/IO



(Pediatric dose per weight/length-based system)
(May repeat 15 - 45 minutes after initial dose if patient begins to develop muscular "twitching" or movement)


GUIDELINES FOR HELICOPTER TRANSPORT
Several factors must be considered before summoning an aero medical helicopter for a scene response. Stable patients who are accessible by ground vehicles are best transported by ground vehicles. Often, patients can be transported and delivered to local hospitals before a helicopter can reach the scene. Most emergencies can be adequately stabilized in local hospitals, and transferred, if necessary, to a level 2 Trauma Centers later.
Helicopter transport should be considered in the following cases:
1. Transport time to local hospital by ground ambulance is greater than aero medical (>60 min)
2. Patient extrication time greater than 20 minutes.
3. Number of critically ill or injured patients exceeds capabilities of local EMS agencies.
4. Ambulance access to the scene, or away from the scene, is impeded by road conditions, weather conditions, or traffic.
5. Patients who have special problems or needs which require treatment in a specialized tertiary care facility including:

  • STEMI patients

  • Stroke patients

  • Spinal injuries with paralysis or lateralizing signs

  • Burns of greater than 10% body surface, or burns which involve the face, hands, feet, or perineum, or burns with significant respiratory involvement.

  • Electrical shock injuries/lightning injuries

  • Amputation of an extremity

6. Estimated ground transport time to local hospital exceeds 15 minutes and the

patient has one of the following injuries or conditions:
Significant Mechanism of Injury:


  • Automobile rollover with unrestrained passengers

  • Automobile versus pedestrian at greater than 10 MPH

  • Falls from greater than 15 feet

  • Motorcycle victims ejected at greater than 20 MPH

  • Death of occupant in same vehicle

  • Ejection of patient from vehicle

Patient Conditions:



  • Penetrating injury to head, neck, chest, abdomen, or groin

  • Two or more proximal bone fractures

  • Burns > 10% BSA

  • Flail chest

  • Pediatric multiple trauma

Once you determine an ALS ROTOR WING ambulance is needed, dispatch them through your dispatcher. Dispatch them early so that their speed can be utilized. REMEMBER, they can always be canceled.


If the patient is ready to be transported and the ALS ROTOR WING ambulance’s ETA is prolonged, consider making arrangements to meet the ALS ambulance ENROUTE to the medical facility.
When or if the determination has been made that the ALS Helicopter is not needed, cancel them through state radio.
All EMS and Fire Rescue personnel will trained in the safety procedures of ALS ROTOR WING ambulance landing, approaching, loading, unloading and take off. Use those procedures at all times when utilizing ROTOR WING ambulances.

12 LEAD ACQUISITION AND TRANSMISSION PROCEDURE
Indications:

  • EMT/AEMT’s will obtain a 12 lead EKG on all patients with medical complaints, 14 years and older. This 12 lead EKG should be obtained within 10 minutes of patient contact and immediately transmitted to the receiving hospital. Do NOT delay emergency treatment such as oxygen and nitro to obtain the 12 lead EKG.

Procedure:

12 lead Acquisition

  • Determine the patient is a medical patient over the age of 14.

  • Place patient in a seated or lying position as you want the patient to be comfortable and relaxed as possible.

  • Explain the procedure to the patient.

  • Turn on monitor and attach the 12 lead cable. Separate the cables and attach electrodes to each lead prior to placement of the patient. Use fresh electrodes, check expiration date and center of electrode for moisture.

  • Remove clothing above the waist.

  • Prep the skin by rubbing it with a alcohol pad, towel or 4X4. Shave patient if excessive hair in on the chest, being careful not to nick the skin.


Lead Placement

  • Limb leads should be attached to the limbs, on the shoulders (deltoids) or wrist and the lower legs flat surface just above the ankles or hips.

  • V-1 Attach electrode at 4th intercostal space right of the sternum

  • V-2 Attach electrode at 4th intercostal space left of the sternum

  • V-3 Attach electrode between V2 and V4 after you find V4 landmark

  • V-4 Attach electrode in the 5th intercostal space midclavicular line (beneath the breast not on the breast)

  • V-5 Attach electrode in the 5th intercostal space level with V-4 at left anterior axillary line or between V-4 and V-6

  • V-6 Attach electrode in the 5th intercostal space at the midaxillary line level with V-4 and V-5.

  • Leave electrodes on until you arrive at the ER.




  • Ask patient to hold very still but not hold their breath. Patient should not cross their legs. Make sure leads are not moving or being held by patient. Inform the patient this will only take about 10 to 12 seconds.

  • Obtain the 12 lead tracing by pushing the 12 lead button on left side of monitor. You must enter the patient’s age and sex before the 12 lead will start.

  • When the 12 lead is complete a copy of the 12 lead tracing will print.

  • Push the Transmit button on bottom left, then select “site” and select the appropriate hospital receiving facility then push “send”.

  • Leave electrodes on the patient, so serial (repeat) 12 leads can be obtained.

  • Contact the ER at the receiving facility to confirm they have received the 12 lead and for any further orders.

  • Continue caring for patient using the appropriate medical protocol.


Trouble Shooting:
If you are having trouble obtaining the 12 lead or transmitting the EKG, check the following:

  • One of the biggest problems with obtaining a 12 lead is movement of the cables.

    • Check to make sure cables are not moving,

    • under the wheel of the gurney

    • or pulled lose from the patient.

  • Stop the ambulance for the few seconds it takes to obtain the 12 lead.

  • If the wireless connection is not connected or the signal is too weak, the transmission will resume when a better signal is found. So a 12 lead may go partially though then continue when the signal is sufficient. (such as dead spots)

  • Electrodes will not stick well to patients who are diaphoretic, dry the skin with a towel before putting electrodes on.

  • Artifact will affect the 12 lead EKG. Move cell phones, pagers, radios away from the monitor if you are getting a tracing with artifact. Ceiling fans, electric blankets, or other electronics can cause artifact.

Documentation:

  • Attach a copy of the 12 lead EKG to your run report at the end of each call. Include the patients name and the run number at the top of the 12 lead EKG.


USE OF THE LUCAS DEVICE

TO PROVIDE EXTERNAL CHEST COMPRESSIONS IN PATIENTS SUFFERING CARDIAC ARREST
Purpose
This procedure describes the appropriate methods to apply, operate, and discontinue the LUCAS device in patients > 12 years of age requiring mechanical chest compression related to cardiac arrest.
Indications


  1. The Lucas may be used in patients 12 years of age and older who have suffered non-traumatic cardiac arrest, where manual CPR would otherwise be used.


Contraindications


  1. Patients < 12 years of age.

  2. Patients suffering traumatic cardiac arrest or patients with obvious signs of traumatic injury.

  3. Patients who do not fit within the device.

    1. Patients who are too large and with whom you cannot press the pressure pad down 2 inches.

    2. Patients who are too small and with whom you cannot pull the pressure pad down to touch the sternum


Protocol for Placement


  1. All therapies related to the management of cardiopulmonary arrest should be continued as currently defined

  2. Initiate resuscitative measures following protocol

    1. Early defibrillation should be considered and provided as indicated based on clinical presentation.

    2. Manual chest compressions should be initiated immediately while the LUCAS device is being placed on the patient.

    3. Limit interruptions in chest compressions to 10 seconds or less.

    4. Do not delay manual CPR for the LUCAS. Continue manual CPR until the device can be placed.

  3. While resuscitative measures are initiated, the LUCAS device should be removed from its carrying device and placed on the patient in the following manner.


Back plate Placement

    • The back plate should be centered on the nipple line and the top of the back plate should be located just below the patient’s armpits




  • In cases for which the patient is already on the stretcher, place the back plate underneath the thorax. This can be accomplished by log-rolling the patient or raising the torso (Placement should occur during a scheduled discontinuation of compressions [e.g., after five cycles of 30:2 or two minutes of uninterrupted compressions]).


Position the Compressor


    • Turn the LUCAS Device on (the device will perform a 3 second self test).
